Latest Patents

One of Hak-ki Choi's latest patents is titled "Methods for resetting and driving plasma display panels in which address electrode lines are electrically floated." This method involves a wall charge accumulation operation and a wall charge distribution operation. During the wall charge accumulation operation, the voltage applied to second display electrode lines is gradually increased to reach a first voltage. In the wall charge distribution operation, while the voltage applied to the first display electrode lines is maintained at a second voltage lower than the first voltage, the voltage applied to the second display electrode lines is gradually decreased to reach a third voltage lower than the second voltage, and address electrode lines are electrically floated.

Another notable patent is "Apparatus for driving plasma display panel performing address-display mixing driving scheme." This apparatus includes a scan electrode drive that features a switching output circuit, a reset/sustain circuit, an upper scan circuit, a lower scan circuit, a first switching circuit, and a second switching circuit. The switching output circuit comprises upper transistors and lower transistors, each paired with corresponding upper transistors, and the common output lines are connected to the scan electrode lines.
